Cashbox can mean:

In common language cash refers to money in the physical form of currency, such as banknotes and coins.

In bookkeeping and finance, cash refers to current assets comprising currency or currency equivalents that can be accessed immediately or near-immediately (as in the case of money market accounts). Cash is seen either as a reserve for payments, in case of a structural or incidental negative cash flow or as a way to avoid a downturn on financial markets.

The word is variously attributed. Some claim that the word "cash" comes from the modern French word caisse, which means (money) box, from the Provençal word caissa, from the Italian cassa, from the Latin capsa all meaning box. In the 18th century, the word passed to refer to the money instead of the actual box containing it. Another claim is that it was derived from Tamil word kāśu (Tamil: காசு) meaning a coin, by East India Company.Kāśu itself is derived from kārṣāpaṇam, a currency which was used by the Mahajanapadas in 6th century BC.

"Cash" used as a verb means "to convert to cash"; for example in the expression "to cash a cheque".

Box (plural boxes) describes a variety of containers and receptacles for permanent use as storage, or for temporary use often for transporting contents. The word derives from the Greek πύξος (puxos), "box, boxwood".

Boxes may be made of durable materials such as wood or metal, or of corrugated fiberboard, paperboard, or other non-durable materials. The size may vary from very small (e.g., a matchbox) to the size of a large appliance. A corrugated box is a very common shipping container. When no specific shape is described, a box of rectangular cross-section with all sides flat may be expected, but a box may have a horizontal cross section that is square, elongated, round or oval; sloped or domed top surfaces, or non-vertical sides.

A decorative or storage box may be opened by raising, pulling, sliding or removing the lid, which may be hinged and/or fastened by a catch, clasp, or lock.

Several types of boxes are used in packaging and storage.

Depending on locale and specific usage, the terms carton and box are sometimes used interchangeably.
